Re: Pi4 1GB Availability? US Distributor Shows It As Discontinued

I'm assuming for $35 you get 2GB and for $55 you get 4GB, or are both models being decreased by $10? Maybe they ran out of the memory chips used for the $35 model. Hopefully this also means an 8GB model is on the way so one can retain the 35/45/55 pricing scheme. On the other hand, given the supply...

No idea. It's difficult to get a Zero to 80 without some pretty intense workloads.
That's my experience too. This thread

Re: New Pi 4B v1.2?

I doubt it. AIUI, the Pi 4 doesn't support USB-PD, it just requires 5V at 3A to be delivered. If that requirement needs to be negotiated, or the port can't supply it -- and the Wikipedia entry is a little hazy on this -- the Pi 4 won't boot. All that's been fixed is the odd resistor setup which fla...
